Well, since you like quoting from the manual, if you read a little bit further on, you can find the answer to your question: "Prepared statements are so useful that they are the only feature that PDO will emulate for drivers that don't support them. This ensures that you will be able to use the same data access paradigm regardless of the capabilities of the database.
